ASTM F1671 Standards

Importance of ASTM F1671

ASTM F1671 is a critical standard for selecting protective gowns in healthcare settings. Following FDA guidance, choosing the right barrier is a non-negotiable safety standard in the medical field. This standard evaluates the resistance of protective clothing materials to viral penetration. By adhering to ASTM F1671, you ensure that the gowns you choose provide adequate protection against bloodborne pathogens and other dangerous pathogenic microorganisms.

Ensuring your product meets these stringent ASTM safety standards guarantees reliable barrier protection. This means the garment maintains exceptional liquid barrier performance even under pressure. The testing process simulates viral penetration using a surrogate microbe, specifically the Phi-X174 bacteriophage.

This bacteriophage is similar in size and shape to deadly viruses like the Hepatitis C virus, Hepatitis B virus, and Human immunodeficiency virus (HIV). The results from these tests guide you in selecting gowns that effectively prevent viral transmission.

Surrogate Microbe	Phi-X174 Bacteriophage
Similar Viruses	Hepatitis C Virus (HCV), Hepatitis B Virus (HBV), Human Immunodeficiency Virus (HIV)
Purpose	Assess resistance of protective clothing materials to viral penetration

Understanding Different Gown Levels (Level 1 to 3 vs. Level 4)

Before diving into the highest tier of protection, it is important to understand the baseline. Level 1, Level 2, and Level 3 gowns are typically evaluated using hydrostatic pressure tests to measure their resistance to fluids. These lower-tier garments are often used as standard isolation gowns, general medical gowns, or basic hospital gowns for minimal to moderate fluid exposure. However, when it comes to major surgery or environments with a high risk of blood exposure, these lower levels do not offer the viral barrier required to keep healthcare workers completely safe.

The ANSI/AAMI PB70 Framework

To fully grasp these levels, the medical community relies on the ANSI/AAMI PB70 guidelines (often referred to simply as the AAMI standard or ANSI/AAMI). The ANSI framework establishes objective barrier protection levels based on anticipated fluid exposure risk. When evaluating gown classification for Levels 1 through 3, the focus is largely on basic disposable patient gowns and standard disposable medical isolation gowns (widely marketed as Medical Isolation Gowns). To determine overall gown performance, testers measure impact penetration and fluid strikethrough. If a gown passes these tests, it proves it can handle basic fluid contact—but not necessarily viral penetration under pressure.

Key Features of Level 4 Gowns

Level 4 gowns stand out due to their superior protection against viral penetration. These gowns undergo rigorous testing to ensure they meet the highest standards of safety. Here are some key features that distinguish Level 4 gowns from lower-level options:

Feature	Level 4 Gowns	Lower-Level Gowns (1, 2, 3)
Fluid Penetration Resistance	Prevents all fluid penetration for up to 1 hour	Not impermeable to viral penetration
Testing Standard	Tested for viral penetration resistance using ASTM F1671	Tested only for water resistance
Protection Level	Considered impermeable to viral penetration	Provides increasing resistance to liquids

Using Level 4 gowns is essential in high-risk medical procedures. These gowns are designed with multi-layer nonwoven fabric, offering strength and fluid resistance. They provide a high fluid and viral barrier while ensuring comfort and breathability during long procedures.

The documented benefits of using Level 4 gowns include:

• Multi-layer nonwoven fabric for enhanced strength and fluid resistance.

• High fluid and viral barrier with advanced polymer layers.

• Comfort and breathability during extended use.

You should consider Level 4 gowns for procedures such as:

1. Trauma and transplant surgeries

2. Cardiac and orthopedic operations

3. Neurosurgery and long-duration procedures

4. Infectious disease control and isolation units

5. Emergency response and ICU interventions

Global Standard Comparisons: AAMI vs. EN Norms

When selecting a high-tier Sterile surgical gown, evaluating the material quality is paramount. Top-tier garments utilize advanced fluid resistant materials, typically engineered from NON-WOVEN polypropylene or multi-layered SMS fabric. But how does this stack up internationally? A Level 4 gown under American AAMI standards offers a comparable—and sometimes superior—level of protection to European en 13795 high-performance gowns. In extreme high-risk scenarios involving severe biohazards, facilities might also look toward full-body EN14126 Class 5-6 protective suits or en14126 Class 5-6 coveralls to ensure maximum viral defense.

By understanding the importance of ASTM F1671 and the features of Level 4 gowns, you can make informed decisions that enhance safety and reduce the risk of cross-contamination in healthcare environments.
